Dave?.

Thanks, Rob. Good morning, everyone, and thanks for joining us to review our financial results for the first quarter of '23 and to cover some recent updates, then we'd be pleased to take any questions.

In the first quarter, we continued to enroll more patients in our Phase 2b clinical trial of our oral ibezapolstat, our lead antibiotic candidate for the treatment of patients with C.

difficile infection although 2b trial is a randomized 1:1 non-inferiority double blind trial of oral ibezapolstat compared to oral vancomycin, a standard of care to treat C. difficile infection. The primary endpoint is clinical cure at the end of treatment and a secondary endpoint is sustained clinical cure measured at day 38 follow-up visit.

Since this is a double-blind trial, results won't be known until the end of the trial. However, operationally, the trial is proceeding as expected with no safety signals reported to date and the blinded observed data has been exceptional.

The phase 2b trial protocol includes an exploratory endpoint comparing the impact on the microbiome between ibezapolstat and vanco. In the event non-inferiority of ibezapolstat to vanco has demonstrated further analysis will be conducted to test for superiority.

Due to slower than enrolment expected during the COVID-19 and its aftermath, we expanded the number of clinical trial sites participating in the Phase 2b trial from the initial 12 sites to now we have a total of 28 trial sites.

Most importantly in March 2023, the FDA accepted our protocol amendment to our IND, which will allow an independent data monitoring committee, which we've assembled to review interim clinical data upon reaching 36 patients enrolled and then to provide its recommendation either to early terminate the 2b trial as we had done with the 2a trial, you may recall, or alternatively continue enrolling.

We anticipate completing enrollment of the 36 patients in the second half of '23. The company intends to report available data properly after the IDMC conducts this interim review. The company has - we remain particularly excited about the dual impact of ibezapolstat to treat C.

diff infection while appropriately managing the long term care of each patient's microbiome, which we believe is exceptional for antibiotic therapy. Other key highlights from the first quarter of '23 or in some cases shortly thereafter include the following.

In April '23, two presentations were made at the 33 Annual ECCMID Conference in Copenhagen, Denmark. First, a scientific poster entitled "Novel Pharmacology and Susceptibility of Ibezapolstat Against C. difficile Isolates with Reduced Susceptibility to C. difficile-directed Antibiotics" was presented by Dr.

Kevin Garey, Professor and Chair, University of Houston College of Pharmacy, and Principal Investigator for microbiome aspects of our ibezapolstat clinical trial program. Dr. Garey's work demonstrated that it ibezapolstat's mechanism of action is not only bacterial target to C.

diff but also inhibit some of its virulence mechanisms, meaning its capability to cause disease. Dr. Garey also noted that C. difficile strains will reduced susceptibility to metronidazole, vanco and fidaxomicin were in fact susceptible to ibezapolstat. Ibezapolstat's anti-virulence effect, namely reduced flagellar movement of the C.

diff organism was a positive unexpected finding reflecting the unique mode of action in inhibiting DNA pol IIIC.

The second of the two ECCMID Presentation was by our Chairman, our Executive Chairman, Bob DeLuccia, who presented an update regarding the company's preclinical systemic oral and IV program for treatment of other gram positive infections caused by MRSA, VRE and DRSP at the pipeline corner, featured session at ECCMID organized by Dr.

Ursula Theuretzbacher, a world renowned microbiology expert in antibacterial research.

Following the clinical validation of the pol IIIC bacterial target in our Phase 2a trial showing 100% cures with no re-infections, we've made significant improvements in cytotoxicity, solubility and protein binding in vitro, and in vivo safety and have demonstrated oral and IV efficacy in a number of mouse infection models.

Both the poster and the presentation are available on our website.

Additionally, we wanted to mention Dutch sponsorship, the company has continued its R&D collaboration with Leiden University Medical Center in Holland under a previously awarded grant from the Dutch government of approximately a $0.5 million to further evaluate the mechanism of action of our inhibitors against the DNA pol IIIC enzyme which is the bacterial target of our antibiotic pipeline for the systemic treatment, IV and oral of gram positive bacterial infections.

Data generated from this program was critical to include in a recent non-dilutive grant application to CARB-X, which I'll describe in more detail in a moment.

But based on this successful collaboration, we're hoping to receive an additional two-year grant for more research in this regard, which if it comes through, we're expecting in the middle of the year and it would be in the range of $800,000 for this second component. Let's now turn to CARB-X.

We remain in the running for funding our second antibiotic candidate targeting the treatment of MRSA infections by CARB-X and we expect a final decision no later than October of this year.

Just to reflect on how this came about in October of '22, we applied to CARB-X for a non-dilutive grant of up to $11.3 million which if approved would provide funding for our second antibiotic program targeting MRSA infections for a period of five years up to the start of Phase 2 clinical trials.

CARB-X recently informed us that our application is in the active review pool and the final decision is to be rendered by CARB-X no later than October 23.

We believe that based on our recent development progress and the unique nature of having a new class of antibiotics together with our understanding that CARB-X already made final decisions on most candidates, we remain under active review.

For these reasons, we believe we have a strong possibility to gain CARB-X approval for funding later in the year. If approved, CARB-X will fund the $11.3 million of a $16 million project and that would cover oral and IV formulations of our second antibiotic candidate ACX-375.

Now just looking ahead a bit the AMR Congress later this year in September, the World-Antimicrobial Resistance Congress will convene its annual meeting in Philadelphia, where experts in the field from both public and private sectors weigh in on the latest innovations to address AMR.

Our Executive Chairman Bob DeLuccia was invited to and will speak at the Innovative showcase section of the conference and will present an update entitled novel DNA poly IIIC inhibitors for gram-positive bacterial infections preparing for the next pandemic. After the presentation, it will be available on our website.

Also looking ahead a bit, we'd like to mention the PASTEUR Act. Last month, U. S. Senators Michael Bennet from Colorado and Todd Young, reintroduced the PASTEUR Act, pioneering antimicrobial subscription is to end up searching resistance.

To encourage innovative drug development targeting the most threatening infections, improve the appropriate use of an antibiotics and ensure domestic availability of antibiotics when needed. According to Senator Bennett, the bipartisan PASTEUR Act is the strongest bill ever written to strengthen antibiotic development and use.

It will fix our market failures, expand the pipeline for next generation antibiotics and save lives. If approved, PASTEUR Act has the potential to enhance the commercial prospects for our antibiotics by providing funding for our Phase 3 clinical trials in stockpiling our antibiotic at public health facilities in the U.S.

each year for 5 to 10 years, as currently drafted designation as a critical need antimicrobial under the PASTEUR Act if approved would apply to sponsors of antibiotic candidates, which are a new class of antibiotics and that target a treatment of serious or life threatening infections as is the case with our lead antibiotic candidate ibezapolstat.

Accordingly, we're quite enthusiastic about the prospects of the PASTEUR Act being passed into law. Now back to our CFO, Rob Shawah, to guide you through the highlights of our financial results for the quarter.

Rob?.

Thanks, Dave. Our financial results for the first quarter ended March 31, 2023 were included in our press release issued earlier this morning. The company ended the first quarter with cash totaling $7.2 million compared to $9.1 million as of December 31, 2022.

Research and development expenses for a three months ended March 31, 2023 were $1 million compared to $800,000 for the three months ended March 31, 2022. The increase was due to Phase 2b trial related costs.

General and administrative expenses for the three months ended March 31 were $1.9 million compared to $1.9 million for a three months ended March 31, 2022.

The company reported a net loss of $2.9 million or $0.25 per diluted share for a three months ended March 31, 2023 compared to a net loss of $2.7 million or $0.26 per diluted share for the three months ended March 31, 2022. The company had 11,671,795 shares outstanding as of March 31, 2023. With that, I'll turn the call back to Dave..

Thanks, Rob. And to all of you joining us today. As you've heard, we've kicked off 2023 with advances in several areas that we believe will spur continued growth and momentum to build on our strong fundamentals. We look forward to sustaining this momentum even during these challenging times and sharing future updates in the coming months.

I'll now open the call for questions.

Operator?.

[Operator Instructions] Our first question comes from Ed Arce with H.C. Wainwright. Please proceed with your question..

Hi, good morning everyone.

This is [Thomas] here asking couple questions for Ed, perhaps first question regarding the...?.

Good morning..

Good morning to see continued progress in the Phase 2b study. So and it's our first question, the interim analysis that will be trigger with the enrollment of the 36 patient, as you mentioned earlier. It was previously expected in mid-year and now second half of 2023.

Can you discuss, what, are some major factors behind this change?.

Well, thanks, Thomas I appreciate the question. We're really putting our finger in the air if you will. As we sit here today, it's close to midyear right now, right it's May 12. So are we going to be done by the 4th of July, could very well happen. Our Chairman would say, it's definitely going to be done in the third quarter.

But he's the one that's in charge of R&D. So I like to think its second half and this way we have a nice conservative cushion..

I see that makes sense.

And can you talk about other than the primary efficacy endpoint, what other efficacy can investors look for in this interim analysis?.

Well, I mean, we'll know when we see the data, but we're fairly certain we're going to see something between 90% and 100% efficacy out of our side of the study. Given that we were 100% in the 2a. It's one-to-one randomized.

So based on 60 years of data, we're going to expect to see something around 85% in that area for oral vancomycin and the primary endpoint and the treatment and that if we expect it to slip possibly significantly from there at the follow-up visit.

What I can also say is for the first time that we've seen, we're testing a portion of the patients for all the way out to 90 days after the end of treatment. And we expect to see that our drug is, not going to be having any re-infections even that far out..

Great. Thanks for - the additional detail. That's certainly important considering the microbiome aspect of these patients. And then perhaps one more question from us regarding the CapEx grants I recall previously a decision was expected in April and now it's October.

Does that mean your events to be mix round and what type of announcements should we expect?.

Well, we understand that their decision will be rendered no later than October, pending the outcome of their omnibus capital call that they referenced basically their annual fundraising effort. So what we're told is that, most of their decisions have been made already. And as you may expect, most of those decisions were rejections.

And sure a handful, I'm sure we've got through, but we're still in the actively pending pool. So, we're really excited by that. I mean, for folks that thought that perhaps it was a small possibility going into the last conference call. I think our chances are a lot higher than maybe people originally thought.

Of course, we were uniquely advantaged by knowing how much development had happened. So, we were particularly enthusiastic going into the process, because we're real close with lead optimization now..

All right..

That's a little of the color behind it but....

Okay. Thank you so much for taking our questions and looking forward to the interim analyses and best of luck on the CapEx decision as well..

Thank you so much, Thomas..

Our next question comes from Jim Molloy with Alliance Global Partners. Please proceed with your question..

Hi, good morning. Thank you for taking my questions..

Good morning..

Good morning, David. One of the comments you made in your prepared remarks was the blinded data is exceptional.

Could you expand a little bit on that as the blinded data how exceptional it can be or you can know how exceptional it is?.

Yes, I mean, we have almost all cures that we see. It's blinded data so we don't know which patients are in which baskets. But - so for people that are thinking that one of the possibilities at the interim review could be futility. The answer to that is, if every last remaining patient is a negative outcome from here forward.

I don't see futility having any possibility. So it's all really good and the patients that are cured are going out 90 days without re-infections. So it's data that we haven't seen the likes of in this space as we've reviewed it over the past few years..

And I guess on the patients have been in to-date it's been one-to-one active versus vanco and they've been holding - true to that or didn't you know the ratio?.

It's one-to-one, Jim, but its one-to-one randomized at the clinical trial site level. So, as you kind of boil that all the way up to, the data center, it may be one or two patients different than that. So when we get to 36, it could be that we're 20 and 16 or 19 and 17.

It just really depends on if we have, say a trial site that enrolls five patients, they're going to have three in one and two in the other. So, if you have the same disproportion in one other site maybe that's six and four. So it could be a little off. Of the 18 and 18, but it will be close..

Okay. And so this - you start to get to the heart of this is what you're meaning when you're saying they look exceptional. As far as you guys can tell, everyone's getting cured.

So assuming that the 1-1 randomization is pretty true or close enough to true, it would seem unlikely that you're not having an effect?.

Yes, there's no chance, there's no chance that we're not having an effect. There's, a real, real lot of cures. I could tell you that..

It seems like the vanco is doing pretty well as well.

Just traditional cure rates for vanco?.

Well, there's about 60, here is a clinical data on vanco, I've seen it as low as 79% and as high as 92%. And so, that's why we expect something in the mid-80s and, I haven't seen anything to shake my confidence that it's going to be in the mid-80s..

Got it. And then can you speak to the unique challenges on the Phase 2b recruit. Pick the Phase 2a, I think you started that in March 2020 at top-line data at the end of the year. Maybe I have that timeline incorrect.

So what are the challenges on the 2b that you guys are able to avoid in the 2a for recruiting?.

Well, as time has gone by, the culture of clinical trials has changed. So there is more telemedicine there's less people that are deciding to go to the doctor at the trial sites. You have varying degrees of physical presence - at the site with the site administrator and the principal investigator on the same day.

And you also have patients that uniquely with a C. difficile trial need to get to the trial site within 24 hours of being diagnosed. With C. diff so if the patient is at a referring physician site in Fort Lauderdale, for example, Monday at noon they're diagnosed with C. diff they have to be willing to go to Miami.

And then they have to agree to go back to Miami 10 times over a two-month period. So that's - it's because of the trial design in part and largely due to COVID. And interestingly, Jim, I should say there have been a number of patients who could have gotten in, but at the last minute, they qualify. But they had COVID and decided not to participate..

Understood, all right, great. And maybe last question on my end.

What does - or last couple of questions, what is active sort of review mean and what other things of [Carvex] fund, do you know offhand which is already approved or agreed to fund?.

Well, they're not. I look at the Carvex's website, which folks can do in that. I haven't noticed that they put anything up yet. And I think that's probably because once a company gets approved, we'll never of course know how many got rejected, but you can imagine it's like probably over 90% get rejected.

But those that, get approved, the approval is subject to negotiation and execution of definitive agreements, which usually will take a 30-day period. So if you check that website, the Carvex website in about a month, I think you'll probably see..

Perfect. And then in line - what should we be looking for on the Pasteur Act? I know it's in the Senate and I concern to be slow.

What are you guys watching for as you're trying to see if this thing gets through?.

It's the government and you know how those things go. But from our position in the antimicrobial working group, the expectation is at the end of the third quarter, they expect it to be included in a piece of legislation..

Thank you..

Oh no problem, just to clarify a little bit more, my personal view, because of the budget battles and stuff like that that are going on. Even though this is bipartisan supported in both houses of Congress, I think they're going to come through with Pasteur Light, which would be instead of $750 million to $3 billion for the sponsor over 10 years.

I think it will be approved as more like $375 million to $1.5 billion over 5 years. That's just my educated guess..

Certainly, good numbers either way..

From where we sit today, it's irrationally exceptional for us and great for public health..

Indeed. Thank you, David, for taking the questions..

No problem, Jim. Thank you..

[Operator Instructions] Our next question comes from Nick Meyer. Please proceed with your question..

Good morning, Nick..

Good morning, hi. How are you doing, David? Thanks for the clarification so far on the conference call.

One question I do have is have you started seeing enrollment pick up now that COVID is fully subsided and - the COVID restrictions and the pandemic is "officially" came to the end?.

No, no we haven't I mean, what we've seen tick up is more pre-screening. So, we have more patients that were able to get into the pre-screening process. So it's probably about the same in terms of the patients that get through pre-screening successfully and choose to be in the study..

Okay. It's the same included. Okay. One thing that - I've wondered is the Phase 2a rate seemed to have been a lot faster than what we've seen in Phase 2b. I just wanted to know, and that was during COVID.

So I just want to know what the disparity was, but it seems like it's still just COVID-related?.

Yes, it's still COVID-related and as people, I mean, COVID the aftermath of COVID, I guess we could call it, it's such that less people are still going to the doctor, to the hospital. People are more focused on things like bacteria and avoiding it.

There's more telemedicine and a lot of the sites are operating remotely like the rest of the world, operates remotely instead of kind of going into the office all the time.

So these are all challenges, which are heightened by our trial design, which by necessity, the patient has to get into the study within 24 hours, because they have a life threatening infection. So it would be medically unethical to have them hanging out with C. difficile that could kill them for a long period of time without being treated..

Okay. Yes, thank you that's all. That's the only question I had..

Excellent, well, thanks for the question then..

We have reached the end of our question-and-answer session. This concludes today's conference. Thank you for your participation. You may disconnect your lines at this time..

Thanks, Maria..
